Hi Olesya,
Thanks for reaching out. For UACs except the engagement type you could download stats by querying reports from this list in Adwords API. Please let me know if you have any other questions.
Thanks and regards,

Hi Olesya,
The UAC engagement reporting is not supported in the Adwords API. However, you would be able to do the campaign level reporting for the UAC engagement in Google Ads API. Please let me know if you have any further concerns.
Thanks and regards,
